1. Maintain
   Inspect
2. Upgrade
   Repair

Follow the advice in this inverted work and maintain the things you own, especially your car. Following the guidance in your owner's manual — you know, that book hidden under a pile of napkins in your glove compartment — to keep the wheels turning.

1. Table
   Nugget
2. Luggage
   Timepiece

The word you see here written upside down is nugget, as in the gold nuggets still buried in dirt and rock all over the world. Do you need inspiration to get to mining? In 1869, miners in Australia found the largest gold nugget in history. Weighing in at 173 pounds, it was melted down in the 20th century. Another mega-sized hunk of gold found in Brazil in 1983 weighs in at 134 pounds and is currently the largest gold nugget known to exist.

1. Seeker
   Knees
2. Keen
   Sneeky

In our favorite kids' song, the word upended in this question falls right after head and shoulders and right before toes. Yup, it's knees. The bone covering this bending body part is the patella, not to be confused with paella, which is a delicious rice dish.

1. Fawned
   Friend
2. Flawed
   Drawl

That word turned vice-versa is flawed, as in flawed hero. Need an example? Think no further than the flawed heroes at the heart of famous Shakespearean plays, like the impulsive Romeo, indecisive Hamlet and murderously ambitious Macbeth.

1. Madman
   Madam
2. Wand
   Wedded

Not only is the word madam a palindrome — a word that is the same whether it's written backward or forward — but it also refers to two infamous women. Heidi Fleiss made headlines running an escort service for the rich and famous, while Deborah Jeane Palfrey was dubbed the "D.C. Madam" for managing a similar service in Washington, D.C.

1. Totaled
   Debated
2. Toppled
   Bottled

Hopefully, a refreshing drink was all you needed to help you see that this word is bottled. Speaking of bottled, did you know that people around the world buy 1 million bottles of water every minute and that more than 90% aren't recycled? When it comes to things that are bottled in your own life, consider investing in a reusable beverage container rather than those disposable ones you see everywhere.

1. Park
   Bark
2. Carp
   Dark

You don't have to rotate your monitor to see that this word is dark. While many people are afraid of the dark, you should know that 95% of the entire universe consists of mysterious dark matter and dark energy. This might be a good time to embrace that lack of light, huh?

1. Ripped
   Tripped
2. Flipped
   Dipped

These letters have flipped, which is what this upside-down word says. While this quiz only flips the letters over, some forms of word puzzles might also mirror the letters, ordering them from right to left rather than the left to right technique you're used to seeing. This mirror writing was popular with artist and scholar Leonardo da Vinci, who left behind thousands of tough-to-read texts.

1. Dirt
   Bird
2. Blip
   Ride

Hey, bird is the word! While the stereotypical pirate carries a parrot on his shoulder, this brightly-colored critter isn't necessarily the most impressive bird species out there. Ostriches, for example, might make your jaw drop in surprise. Not only are these flightless birds bigger than a grown man, but they can sprint as fast as 40 mph. That's a 90-second mile!

1. Puzzled
   Doubled
2. Upended
   Provided

The word is puzzled, but we bet you aren't puzzled any longer trying to figure it out! The first jigsaw puzzles were produced in the 1760s by gluing maps onto wood and then cutting the wood into pieces?

1. Imagine
   Woman
2. Yesterday
   Blackbird

Recorded in 1971, John Lennon's "Imagine" — which is the overturned word in this image — became the former Beatles' biggest solo hit. In a 1980 interview, Lennon said the song was inspired by a 1964 book of poetry by "Yoko Ono," and that she should have been given writing credit on the tune from the beginning.

1. Memory
   Monopoly
2. Candyland
   Sorry

It may be written upside down, but those with minds like elephants can see that this word is memory. Did you know that you not only have long and short-term memories but also explicit and implicit ones? Explicit memories are things like your phone number or a friend's face, while implicit ones are experiences, such as riding a bike or balancing on one foot.

1. Dragon
   Monster
2. Unicorn
   Panda

Saphira from "Eragon," Drogon from "Game of Thrones" and that "Hungarian Horntail" from the Harry Potter franchise. Yup, they're all dragons, just like the word shown upside down in this question.

1. Exit
   Midway
2. Carousel
   Stable

The word is midway, as in that area at the fair where game attendants try to get you to try your luck. It's also the name of a key battle in WWII, during which the U.S. Navy defeated Japanese forces at a tiny atoll in the Pacific.

1. Railroad
   Doorknob
2. Baliff
   Mailman

OK, "Little Engine That Could" fans, a close examination reveals that this upside-down word is railroad. Did you know that 1869 was a huge moment in railroad history for the U.S., as a golden spike driven into the ground at Promontory, Utah, marked the completion of a Transcontinental Railroad spanning the nation from east to west?

1. Read
   Deer
2. Reed
   Reel

The word shown here is deer, as in an antlered critter, and not in the vein of "Dear Abby." While there are more than 60 species of deer on Earth, one of the weirdest is the Chinese water deer, which has no antlers but does have insanely long canine teeth that would make any vampire jealous.

1. Debased
   Based
2. Dated
   Passed

Flipping these letters right-side up reveals the word, based, as in, there are a whole lot of tech companies based in Silicon Valley in northern California. The list of companies based is this tech mecca just south of San Francisco includes Apple, Facebook, Google, Netflix, Intel and many other global players in computing and technology.

1. Drained
   Nailed
2. Rained
   Detain

The sun will come out tomorrow even if it rained today, as in the cloud-spilling word shown here. And if you think it rains a lot where you live, be glad you're nowhere near Puerto Lopez, Colombia. This city, which can be found at the base of the Andes, is one of the rainiest on Earth. It gets as many as 500 inches of rainfall each year.

1. Honey
   Funny
2. Money
   Rowed

You are right on the money if you guessed this word is another term for cold, hard cash! Speaking of moolah, paper money in the U.S. is made from cotton fibers, and it contains no wood pulp? That means you can spend away without worrying about all the trees you're sacrificing.

1. Fouled
   Founded
2. Folded
   Defended

This word is defended, and it looms large in war stories, one in particular. You've probably heard the phrase "Remember the Alamo!" But do you know why everyone is so intent on helping to spread the story of this tiny Texas mission? It turns out, a small group of soldiers held off a huge Mexican Army for two weeks in 1836 during the Texas Revolution. Their bravery changed the direction of the war, and Texas soon won independence from Mexico.

1. Mound
   Wound
2. Worded
   Drown

Those flipped over letters that you see spell the word wound, as in a simple scrape, cut or even a more serious skin injury. While good old-fashioned bandages can take care of most wounds, anyone with burns or wounds that won't heal might benefit from cutting-edge smart dressings, which use sensors to monitor an injury then send data about the wound wirelessly to care providers.

1. Dealer
   Leaded
2. Detailed
   Reeled

If you guessed this tumbled-over word is reeled, then you've landed a significant point on this question! Fun fact: The largest fish ever reeled in was a white shark caught off the coast of Australia in 1959. It weighed in at 2,664 pounds. In terms of non-sharks, the most brag-worthy catch so far has been a black marlin caught in Peru in 1969. This massive catch which weighed 1,560 pounds.

1. Driven
   Riveted
2. Directed
   Vented

This word is driven, as in ultra-motivated, or in the purest sense, what you may have done with a car. In a 2018 movie titled "Driven," actor Lee Pace plays John DeLorean, maker of that car-turned-time-machine seen in "Back to the Future."

1. Demanded
   Dreamed
2. Learned
   Admired

This word is dreamed, as in Susan Boyle's choice of "I Dreamed a Dream" from "Les Miserables" for her epic "Britain's Got Talent" audition. And in case you were wondering, both dreamed and dreamt are equally correct when referring to the past tense of dreaming, according to Merriam-Webster.

1. Dabbing
   Grabbing
2. Napping
   Bagging

Napping can make you more alert and productive, according to the National Sleep Foundation. But keep those naps to less than 30 minutes to avoid insomnia at night. While humans are rare among mammals because we are monophasic sleepers — meaning we pretty much only sleep for one long period in every 24 hours — the majority of mammals are polyphasic, which means they routinely take naps.

1. Pewter
   Silver
2. Metal
   Stones

Your mind is like a steel trap if you could tell this word says metal. While metal is used to make many objects, its role in history is so significant that we name entire eras after materials made from different types of metals. For example, there's the Bronze Age, during which man learned to mix copper and tin to make bronze tools between 3,000 and 1,200 BC. It was followed by the Iron Age, during which humans began using iron or melting it with carbon to make steel.

1. Dazzling
   Puzzle
2. Delicious
   Drizzle

When it's not quite raining hard enough to call it a downpour, you might use the word drizzle, which is what this turned over word says. Drizzling is also a technique used in cooking, such as drizzling olive oil over a plate of tomatoes and mozzarella, or drizzling gooey hot fudge over an ice cream sundae.

1. Yellow
   Meadow
2. Dwelled
   Folly

The "Y" in ROYGBIV, a memory device used for recalling the order of colors in the rainbow, stands for yellow — the inverted word shown in this question. Of course, you might have another way of remembering the colors of the spectrum, such as the Bible-inspired "Read Out Your Good Book In Verse."

1. Spend
   Deepest
2. Slept
   Speeded

Only the zippiest upside down readers can easily decipher this word as speeded. Speaking of speed, did you know that Germany's Autobahn has no official speed limit? You can also put the pedal to the metal on the Isle of Man. Are you looking to hit the gas in the U.S.? The highest speed limit can be found on a stretch of Route 130 in Texas, where 85 mph is the posted speed.

1. Fret
   Pickup
2. Moped
   Body

The word you see inverted in this question is pickup. Fun fact: The pickup truck, rather than a sedan or SUV, is the bestselling vehicle in the United States. The Ford F-150 has outsold every U.S. car model since its 1975 release and has continued to top the list of most popular American vehicles for more than 40 years.

1. Unicorn
   Unkind
2. Incense
   Reported

You have got to believe in magic just a little if you managed to decipher this word as unicorn, but if you think unicorns are all myth and fantasy, think again. Scientists analyzing fossils of an ancient species called E. sibiricum in 2018 were surprised to find that this "Siberian unicorn" walked the Earth 30,000 years ago. Resembling a furry rhino with a massive, prominent horn on its forehead, it's easy to see why it was the unicorn of its time.

1. Dancer
   Handed
2. Banded
   Panda

You must be an animal lover or a seriously good reader if you could tell that this word is panda. Pandas, known for their gentle nature and black and white coloring, are found only in small areas of China. Fewer than 3,000 remain in the wild, and each of these creatures chows down on 20 to 30 pounds of bamboo every day.

1. Nickel
   Cadmium
2. Helium
   Neon

You can get 20 of these for a dollar, but there's just one nickel shown upended in this question. If you're used to seeing the U.S. 5 cent coin with Thomas Jefferson's face on the front, you may be surprised to learn that the U.S. had an entirely different nickel design from 1913 through 1938. The design with a buffalo on one side and the profile of an "Indian" on the other was discontinued after about 25 years because they wore down very easily.

1. Necklace
   Ball
2. Umbrella
   Balloon

Even upside down, that double "o" and double "n" combo can only be the word balloon! If you happen to be a fan of these colorful party decorations, be warned! The helium used to make balloons float is getting more difficult and expensive to extract from the Earth, so plan on blowing up more of balloons yourself in the future.

1. Drawl
   Walled
2. Mailed
   Dealed

The weirdly-written word you see here is walled, as in walled city. Kowloon City is one of the most infamous examples of this design, with as many as 50,000 people living in an enclosed, lawless area of Hong Kong. At 3.25 million people per square mile, it was the most densely packed area on Earth before it was demolished in the '90s. For a still-standing example of a walled city, check out the picturesque Quebec City in eastern Canada.

1. Mom
   Mow
2. Won
   Wow

This word is wow, as in an exclamation of amazement. It also has an out of this world connection. In 1977, researchers on the Search for Extraterrestrial Intelligence (SETI) project, recorded a 72-second signal sent from deep in the cosmos. Known as the Wow Signal, it's the most compelling evidence ever found that suggests there might be other life forms in the universe.

1. Tailed
   Alien
2. Unable
   Aimed

It doesn't take a rocket scientist to see that this topsy-turvy word is alien. But are aliens out they out there someone? Well, NASA estimates there are 200 billion galaxies in just the tiny portion of the universe we can actually observe, so odds are, intelligent life exists beyond the boundaries of Earth.

1. Dreaded
   Bedded
2. Wedded
   Webbed

The word is webbed. Watch out for those "b"s and "d"s! The word refers to the feet of aquatic animals, where toes are fused to propel the creature through the water. You probably know that ducks have this feature. But did you know it can also be found on some birds, frogs and even kangaroos?

1. Carton
   Dozed
2. Dozen
   Nozzle

This word is dozen, which typically refers to a count of 12 items. Well, unless you're talking about a baker's dozen, in which case, the count increases to 13. Have you ever wondered where this term originated? Well, It turns out, medieval bakers faced severe penalties for short-changing shoppers, so many threw in an extra roll or loaf of bread in each order to stay out of trouble with the law.

1. Hand
   Treat
2. Heart
   Hearing

If you're the romantic type, you probably guessed that this unusually-written word is heart. In humans, the heart is roughly the size of your fist and beats more than 100,000 times a day. It weighs in at under a pound — unless you're a blue whale, of course, because their massive hearts weigh in at 1,500 pounds or more!
